| Metallurgy Work 2006 | | | | Early in 2006 Kings also carried out limited preliminary metallurgical test work on 9 year old Luismin drill core. These preliminary results from comminution test work indicated that the Cerro del Gallo rock is hard and moderately abrasive. Encouraging rougher flotation recoveries of 75% of the gold, 85% of the silver, and 85% of the copper were reported at a grind size of 80% passing 75 microns. Additional results from the test work program indicated rapid cyanide leach kinetics for gold of approximately 85% in 4 hours. Later in the year, Kings engaged SGS Lakefield Oretest Pty. Ltd. of Perth, Australia to carry out comprehensive metallurgical test work on several tonnes of fresh Cerro del Gallo core. | | | |
